In the new issue of Regulation, economist Pierre Lemieux argues that the recent oil price decline is at least partly the result of increased supply from the extraction of shale oil. The increased supply allows the economy to produce more goods, which benefits some people, if not all of them. Thus, contrary to some commentary in the press, cheaper oil prices cannot harm the economy as a whole.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

Under the policy, any vehicle entering an area that has been declared a “Neighborhood Safety Zone” by the city’s police chief can be “stopped for the purpose of determining whether the driver has a legitimate reason for entering the NSZ.”

Here’s an excerpt from the appelate court decision:

We further conclude that appellants have sufficiently demonstrated irreparable injury, particularly in light of their strong likelihood of success on the merits. … The harm to the rights of appellants is apparent. It cannot be gainsaid that citizens have a right to drive upon the public streets of the District of Columbia or any other city absent a constitutionally sound reason for limiting their access. As our discussion of the likelihood of success has demonstrated, there is no such constitutionally sound bar in the NSZ checkpoint program. It is apparent that appellants’ constitutional rights are violated. It has long been established that the loss of constitutional freedoms, “for even minimal periods of time, unquestionably constitutes irreparable injury.” …Granted, the District is not currently imposing an NSZ checkpoint, but it has done so more than once, and the police chief has expressed her intent to continue to use the program until a judge stops her.

It’s time for Mayor Adrian Fenty to show Peter Nickles, the Attorney General of the city, to the door. Too many of his ideas have proven to be misguided and contrary to law.

Last year the Prince George’s County Sheriff’s Department SWAT Team raided the home of Berwyn Heights, Maryland Mayor Cheye Calvo. Police officers on the case knew that dealers were sending packages to random addresses so that accomplices in delivery companies could pick them up. The officers didn’t take the drugs out of circulation at the warehouse when they intercepted them. They simply sent them to the bogus address and raided it. The investigating officers did this without checking with local law enforcement officials, who probably would have told them that the mayor wasn’t a drug dealer and that they were barking up the wrong tree. The SWAT team shot and killed Mayor Calvo’s two dogs and caused significant property damage to his home before they got around to figuring out his (nonexistent) role in narcotics trafficking.

Vice-president Joe Biden says we should rally behind the Supreme Court nomination of Sotomayor because she will “have the back” of the police. Biden is a lawyer, a senator, and former chairman of the Senate’s Judiciary Committee, so he should know better than to pull a political stunt like that to curry favor with law enforcement groups. The Constitution places limits on the power of the police to search, detain, wiretap, imprison, and interrogate. The separation of powers principle means that judges must maintain their impartiality and “check” the police whenever they overstep their authority. To abdicate that responsibility and to “go along with the police” is to do away with our system of checks and balances.

As it happens, The New York Times has a story today about one Jeffrey Deskovic. He got caught up in a police investigation because he was “too distraught” over the rape and murder of his classmate. When there was no DNA match, prosecutors told the jury it didn’t really matter. Does Biden really want Supreme Court justices to come to the support of the state when habeas corpus petitions arrive on their desks and the police work is sloppy, weak, or worse?

On a related note, Cato adjunct scholar Harvey Silverglate fights another miscarriage of justice in Massachusetts.

The TSA and FBI are right: it’s not airport security’s job to look for people like Bonnie Sweeten. But they will quickly agree to make it part of their mission when newspapers and Members of Congress start to say they should. This is how a nominal airline security program transmogrifies into a general law enforcement checkpoint, and the noose tightens on your right to travel.
